Steel Fire Doors for Commercial Projects A Specification Guide
Steel fire doors are specified as complete assemblies. A useful order schedule defines the door leaf, frame, required fire performance, glazing and hardware together. For commercial buildings, getting those details right before production helps prevent incompatible substitutions and installation changes.
Shenghao Doors offers custom steel fire door layouts and finishes for project enquiries. Begin with the project's approved door schedule and performance requirements, then match each opening to a proposed assembly.
Installed double-leaf steel fire door
Confirm the required fire performance first
Our range includes 30-, 60- and 90-minute options for review against the project's requirements. Confirm the applicable report and whether the chosen dimensions, leaf arrangement, glazing and hardware fall within its scope. A time value by itself is not enough to specify a complete fire door.
Different projects can require different performance criteria and evidence. Have the project's responsible designer or approving party identify what is acceptable before ordering. Do not assume one country's documentation provides approval everywhere.
Build a clear door schedule
Schedule item
Information to include
Door location
Door reference, floor and room or corridor
Dimensions
Opening width, height and finished wall thickness
Arrangement
Single leaf, double leaf, fixed transom or vision panel
Opening
Viewing side, hinge side and inward or outward swing
Performance
Required rating and acceptable evidence
Hardware
Hinges, closer, latch, lock and any access control
Mark the same door references on the drawings and packing list. This lets site staff connect each delivered frame, leaf and hardware package to its intended opening.
Choose single and double leaves by passage needs
A single steel fire door can serve everyday staff access where its clear width is suitable. Double leaves can provide a wider passage but require attention to the meeting stile, inactive-leaf hardware and closing sequence. Specify which leaf is normally active.
Door swing should be confirmed using a drawing. Descriptions such as left-opening can mean different things in different markets. Show the viewing side, hinge position and direction of movement.
Review vision panels as part of the assembly
A glazed opening can improve visibility in a corridor or workplace, but its glass, retaining system, size and position must suit the required fire-door configuration. Ordinary decorative glazing should not be substituted into a fire-rated design.
Match the hardware and frame
List the selected closer, latch, hinges and any panic or access-control hardware. Confirm compatibility with the proposed assembly and intended use. Where double leaves need coordinated closing, include that requirement in the schedule.
Review the frame type, wall construction, fixing method, installation clearances and sealing detail before production. The installed result depends on the frame and installation as well as the leaf.
Finish, packing and delivery details
Confirm the colour using a physical sample where finish matching matters. Record door references on the packaging and ask how frames, leaves and accessories will be protected during transport. On arrival, compare the delivered components with the approved schedule before installation.
